Building Practical High‐Voltage Cathode Materials for Lithium‐Ion Batteries

Abstract It has long been a global imperative to develop high‐energy‐density lithium‐ion batteries (LIBs) to meet the ever‐growing electric vehicle market. One of the most effective strategies for boosting the energy density of LIBs is to increase the output voltage, which largely depends upon the cathode materials. As the most‐promising cathodes for high‐voltage LIBs (>4 V vs Li/Li + ), four major categories of cathodes including lithium‐rich layered oxides, nickel‐rich layered oxides, spinel oxides, and high‐voltage polyanionic compounds still encounter severe challenges to realize the improvement of output voltage while maintaining high capacity, fast rate capability, and long service life.
